LOCOMOTIVE SMOKE BOX FRONT Filed Feb. 13, 1929 2 Sheets-Sheet 2 ZwemwPatented Mar. 18, 1930 UNITED rAlrEs HARRY GLAENZER, OF PHILADELPHIA,PENNSYLVANIA LOCOMOTIVE SMOKE-BOX FRONT Application filed February 13,1929. Serial No. 339,653.

My invention relates to certain improvements in the front of alocomotive fire-box which is designed to be hinged to the smokeboX, sothatthe entire end of the smoke-box can be opened, and provided with asmall door opening. In many large locomotives it has become necessary tomount the air cylinder at the end of the smoke-box as well as the belland other fixtures.

The object of my invention is to make the smoke-box front of a steelplate with reinforcing or stiening members welded to the back thereof,and brackets welded to the iront for supporting the fixtures such as airpump bells, etc.

In the accompanying drawings:

Fig. 1 is a View in elevation of my improved smoke-box front forlocomotives;

Fig. 2 is a rear view of the same;

Fig. 3 is a side View;

Fig. 4 is a vertical sectional view on the line 4 4, Fig. 1; and

Fig. 5 is a sectional plan View on the line 5-5, Fig. 1.

The front plate 1 is preferably of steel, circular in form in thepresent instance and having a series of holes near its periphery for thebolts which secure the front to the body of the smoke-box. In the lowerportion of the plate l is a small door opening 2 to allow access to theinterior of the smoke-box,

avoiding the necessity of removing the entire front. Below the opening 2is a plate Shaving hinge butts for a door which closes the opening 2,the plate being welded to the `front.

At one side of the structure is a hingebracket 4, preferably of caststeel, which is welded to the face of the front as shown. On

the bracket are the hinge butts 5*.5 through which a pintle extends onwhich the door swings. The pintle passes through brackets on thesmoke-box (not shown).

Welded to the upper portion of the front is a bell-bracket 6 made fromsheet steel, cut

and bent to form two arms 7, a cross-bar 8 and ianges 9, which arewelded to the front. Welded to the arms 7 are bosses 10 for the belltrunnions.

On the face of the front are two set-s of vertical Z-bars l1-11, whichare welded to 50 the front and are perforated for the bolts which securethe air pumps to these bars which support the pumps. Extending from oneZ-bar to the other of each set is a bar 12, which forms a lip which inturn aids in supporting the pump. This bar is welded to the -Z-bars.While I have shown the bars 11-11 as Z-bars, their cross-section may bevaried as desired. l

In the present instance, on each side of the centre of the plate 1 arewelded thereto `iiag fixtures 13. Welded to the back of the plate 1 arereinforcing braces 14, 15 and 16-16. The'brace 14 is a transverse brace,and the brace 15 is a vertical brace for stiffening the upper portion ofthe plate, while 16-16 are vertical braces for stilening thelowerpor-Vtion of the plate on each side o the door opening 2. The plate 1 is notonly reinforced by the braces at the back of the plate but also by thevertical bars at the front of the plate to which the air pumps aresecured.

These braces may be of any suitable type in cross-section. In thepresent instance I have shown the braces made from bulb angle bars.

The smoke-box front described above can be made comparatively light andvery substantial, and as all the parts are welded to the main plate,there is no liability of the parts becoming loose, eliminating thepossibility of air leaks through omission of bolt holes necessary toconnect parts; much machining is omitted; and the cost of manufactureconsiderably reduced. '3

I claimzs The combination in a locomotive fire-box front plate, of asheet metal plate circular in form, having perforations near-itsperiphery for the bolts by which the plate is secured to t thesmoke-box; two sets of vertically arranged angle bars Welded to the faceof the plate, the bars of each set spaced a given distance apart; asupporting cross-bar extending from one bar of each set to the otherbar,

said bars acting to reinforce the plate; reinforcing braces at the backof the plate, one of said braces extending horizontally directly back ofthe cross-bar at the front of the plate. Y

HARRY GLAENZER.
